a Claims. (01. 18945) 1 This invention. relates to a storm Window and moreparticularly to a-frame adapted to receive removable inserts to form a storm window.

The principal object. of the invention is the provision-of a storm window frame' having sections engageable withxportions thereof to form means for receiving. and retaining glazed or screened inserts.

A further object of the invention is the provision' of a storm window framing member and corner pieces for joining cut and 'mitered sections :to

the framing member to form'a rectangular frame.

A still further object of the invention is the provision of a storm window framing member having means for receiving and retaining modifying strip sections to provide for the reception of glazed'sash therein.

The storm window frame shown and described herein is formed from a master'extrus'ion or metal shape to provide a framing section, cut and mitered sections of which may be used for forming various sizes and shapes of storm Window frames applicable to dwelling house window openings.

The storm window frame includes .channels for receiving modifying strips to alterthe cross sectional shape of the frame for the reception .of glazed sash inserts to be positioned therein and includes means for distorting portions 'of the framing section to lock the said modifyingwsections in place therein.

With the foregoing an'd'other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodimentof the invention herein disclosed can be made Within the scope of what is claimed without departing fromthe spirit of the invention.

The invention is illustrated in the accompanying drawing, wherein:

Figure 1 is a perspective elevation of a storm window frame with parts broken away'a'nd parts incross section.

Figure 2 is a perspective elevation of a corner piece employed in forming the storm window frame illustrated in Figure 1.

Figure 3 is a horizontal cross section taken on line 33 of Figure 1.

Figure 4-. is a horizontal cross section taken on line 44 of Figure 1.

Figure 5 is a perspective elevation of a wedge member used in forming the storm window frame shown in Figures 1, 3 and 4.

Byreferring to the drawings and Figure 11-1111 particular, it will be seen that a dwelling house window opening has been indicated and that the window frame is indicated by the numeral 1-0, the blind stop by the numeral H and the outer casing by thenumeral 12. The sill portion of the frame is indicated by the numeral 13. ;A storm window frame is shown in positionon :the blind stop portion of the window frame and is adapted to be secured in the window opening by 'anyconvenient means. The storm window frame, as illustrated in Figure 1,-consists of aplurality of cut and mitered framing sections 4, each of whichin cross sectional elevation, as illustrated in Figures 3'and 4 of the drawings, ,comprise'a surface flange indicated in Figures 3 and 4 by thenurneral I 4, a section extending at right angles thereto indicated by the humeral 15, thesurface flange having a pair of spaced inturined ribs 16 and-H formed thereon and spaced with relation to the body Jmember' it. The body member 15 has a single outwardly extending 'rib 1.8 on one-'side thereof adjacent the outermost portion of the bodymember l5 and three, spaced, 'parallelJr-ibs I9, 20 and 2| formed on the opposite 'sideof the body member [5 withrespect to the rib| 8.'

The ribs 11 and'l8 forina'channeLin portions of which transversely L-shapedcornervpiecesrfl are positioned at the cut and mitered' corners' of the framing section's M so as to unite them in a frame structure. In Figure 2 of the drawings a perspective'elevation of one of these transversely fiat L-shaped corner piecesis illustrated, and i n Figure 1 one of the corner pieces 2-2 is illustrated in cross-section in position in the channel defined by the ribs '5'! and I8; heretofore referred to.

It willth'us be seen that the main framing section of the storm window frame is so formedas to enable it to be cut and mitered and formed, through the 'use of the corner-pieces 22,'=into1a square or rectangular frame," th'e' outer diameter of which will correspond with the inner diameter of a casingof a dwelling house window toenable a storm window frame to be positioned therein. in order that glazed inserts, such as indicated by the numerals -23 and Figures 1 2'ahd- 3 of the drawings,- maybe positioned in the name, modifying strip sections are added to the framing sections, generally indicated by the numeral l4, and these modifying sections are best illustrated in Figures 3 and 4 of the drawings wherein cross sections are shown.

By referring to these figures, it will be observed that the cross sectional shape of the upper and lower half of the storm window frames are shown and that the shape is altered by the application to the lower half of the frame of modifying strip sections 25 and 26. The modifying strip sections 25 and 26 are similarly formed members, each of which includes an offset, laterally extending portion, which are adapted to respectively engage the spaces between the parallel ribs l9 and 20 and the parallel rib 2| and the surface flange M. In such position, the parallel ribs 20 and 2| are adapted to be moved apart with respect to one another so as to forcefully engage the modifying strip sections 25 and 26 thereby locking them in position in the window frame. Means for moving the ribs 20 and 2| to the locking position is provided and consists of a plurality of wedge members 21, a perspective elevation of one of which is shown in Figure of the drawings.

Still referring to Figures 3 and 4 of the drawings, it will be observed that each of the modifying strip sections 25 and 26 have an axially ext'ending, shallow'groove formed in their surfaces "lying adjacent the rib members 29 and 2| into which shallow groove the ribs 29 and 21 are moved by the positioning of the wedge member In Figure 4 of the drawings the cross section shape of the lower half of the storm window frame is shown and it will be observed that the glazed insert 24 is subsequently installed in the -modifiedframe so that its edges engage the space "between the modifying members 25 and 26 which form oppositely disposed channels in the lower half of the modified frame in which the insert 24 -may move vertically. The space lying between the modifying strip section 26 and the outer edge 2 of the insert 24 is filled with a felt strip 28 which cushions the insert 24 with respect to the frame so formed. It will be observed that in order to position this insert 24 in the storm wind-ow frame,

-' it is necessary to' first place it in the upper half I! of the frame, line it' up with the channel defined "between the modifyin strip sections 25 and 25 and then lower it downwardly into position there- 5 between. In such position, its uppermost edge In Figure 3 of'the drawings the upper insert 23 is shown in position in the frame and it is adapted to be retained in this position by a spring member such as shown in Figure l and indicated by the numeral, one end of which is positioned in the space between the ribs l9 and on the storm window frame.

It will thus be seen that a storm window frame has been disclosed which is primarily formed of a single extruded metallic shape and that this metallic shape, when out and mitered and formed into a frame by the use of the corner pieces 22, is further modified by the application of the modifying members and 26 which are vheld by the wedging action imparted by the abling it to be economically produced.

Having thus described my invention, what I claim is:

l. A storm window framing member including a surface flange and a body section formed at right angles thereto, a plurality of ribs formed on the inner side of the body section forming three channels, modifying members positioned in the lower half of the frame i the outermost of said channels, and means engaged in the other of said channels for distorting the said ribs to move them against the said modifying members so that the distorted ribs hold the modifying members in the framing member, the modifying members forming sash receiving means.

2. A storm window frame comprising an assembly of four out and mitered sections of framing material secured to one another at their ends, each section having a plurality of axially extending ribs formed on the inner side of said framing material and forming three inwardly facing channels therebetween, modifying members positioned in the outermost of said channels in the lower half of the window frame, and means engaged in the other of said channels for distorting the said ribs to move them against the said modifying members so as to cause them to be locked in the storm window frame, the said modifying members forming sash receiving means.

3. Frame element construction for a storm window comprising: a body member including a U-shaped channel; a pair of curved ribs extending from the web of said U in substantially the same direction as the flanges thereof to form three parallel channels; a modifying member in each of the outermost of said channels and adapted to receive the sash of said storm window,
